F g. 5 is a plan view thereof.

' 01' a nut rotatably supported by the cover and In Figs. lto 3 inclusive, l0 indicates aninterscrewed on to a post carried by the body. The nai combustion engine of any well-known type nut extends through a boss carried by the cover and in Figs. 1 and 2, indicates a cartridge-type and the boss is provided with a tubular, projecv filter supported by the engine through the means tion properly threaded at its outer end to receive of suitable straps, while in Fig. 3, I2 indicates a sealed can type filter also supported from the engine III by a suitable strap.

Referring now to Fig. 3, the filter is provided I 10 suitably attached to the engine and communilo construction. The above-described installation is made at the factory at the time and because of the small space available around the engine 7 20 stalling, it is an extremely difficult job to replace 30 and the latter connected to the pipes inthe same The r removable cartridge type filter signed to make it possible to .use it as a replaceot the same type. 40 As clearly shown in Fig. 4, the casing for the filter comprises a cup-shaped body I6 and a of the cover l1 centrally, thereof and is provided with a tubular projection 23 extending at right angles to the axis of the post I9. A nut 24 has a tubular portion 25 extending through the boss 55 22 and collar i1 and having threaded connection the collar 26 coacts with the shoulder 2| to sup: port the filtering unit 20. The passageway in the projection 22 communicates with an annular a ertures 29 with the interior of the filteringunit Likewise, the lower portion of the post I9 is hollow and communicates through theflpastween the upper and lower hollow portion of the post is through the filtering unit 20, the support 2| and collar 26 serving to prevent short-circuiting of flow around the filter unit. The projection 23 is provided with a tapped socket 3| and the post I9 is provided at its lower end with a similarly tapped socket 32.

Replacement of the sealed can filter i2 by the removable cartridge type filter II is made as The bottom elbow fitting l3 originally used with the sealed can filter I2 is screwed into when the sealed into proper position withrespect to the top fitcome spent, the procedure of replacing it with a 30 inserted after which the cover I1 is replaced, the nut 24 screwed on to the post l9 and the pipe H reconnected to the fitting II as previously described. Fig. 5 illustrates in full lines the arrangement of the r jection 22 and the associated elbow fitting l3, in one of two possible positions and in dotted lines illustrates the other possible position. Either of the two positions may be used,

in a position other than horizontal, it may be 'Iherefore, the fitting may be the position shown in full lines in Fig. 5 or the one end bysaid casing and having a passageway tion with the remaining end oi said post, a colsaid body axis.

of said casing, a tubular projection carried by said collar, a passageway connecting the interior of said projection to the interior of said nut, a filter unit supported by said post, passageways in said post for directing liquid from the interior ot'said nut through said filter unit to said first mentioned post passageway, and an elbow fitting mounted on the end of said tubular member with its center line lying in a plane perpendicular to LEWIS W.
